This module provides functions allowing the use of the DW1000 chip with a Raspberry Pi using Python scripts, as presented in this tutorial. It is an adaptation in Python language of the arduino-dw1000 library. This chip embeds Ultra Wide Band (UWB) technology which can be used for message transmissions and more commonly, ranging functionality.

The following external python modules/libraries are necessary for its proper use:

• spidev : This is a standard python module used to interface SPI devices with the Raspberry Pi via the spidev linux kernel driver.
• monotonic (used in the ranging scripts only) : This module provides a function returning the value of a clock which never goes backwards. If you have Python 3 installed on your Raspberry Pi, it is not required since you can use time.monotonic() instead.
• RPi.GPIO : This is the standard python module used to interact with the GPIOs available on the Raspberry Pi.
